Analytics API 400 Bad Request on Custom Report Definition Payload

General Discussion

I’ve spent hours trying to figure out why the Genesys Cloud Analytics API rejects my custom report definition payload with a 400 Bad Request. The endpoint is POST /api/v2/analytics/custom-reports. The ServiceNow integration requires this for automated ticketing triggers. The error message is vague: “Invalid metric definition”. Here is the payload:

{
 "name": "Digital Channel CSAT",
 "metrics": [{"id": "csat-score", "type": "average"}],
 "filters": [{"id": "channel", "op": "eq", "value": "webchat"}]
}

Does the csat-score ID need a specific prefix for digital channels?
